Issues : Annotations in FEJ

b. 18

composition: Op. 45, Prelude in C♯ minor

No accidentals (d) in FE1

 d in FE2

lowering D to D and d1 to d1 in FEJ

Three  D in GE & EE

..

FE1 does not have a single accidental in this entire bar, which means that the diminished chord d-f-a is the harmonic basis. This is how it was understood in FE2, adding a cautionary  before the 1st quaver of the L.H. Chopin's corrections in FEJ and the error-free version of GE show that Chopin's intention here was to have a D major chord as the harmonic basis. The reviser of EE added the relevant naturals here too. Cf. a further note for this bar.

b. 22

composition: Op. 45, Prelude in C♯ minor

g1-a1 in FE (→EE)

a1-b1 in GE & FEJ

..

The fact that FE (→EE) have got a mistaken version here is testififed by the version of GE and a hand-written correction in FEJ.

b. 58

composition: Op. 45, Prelude in C♯ minor

d1-d2 in FE (→EE1)

d1-d2 in GE, EE2 & FEJ

..

The flats lowering d1-d2 to d1-d2 is an error of the engraver of FE1 (→FE2,EE). It is proven by the version of GE and Chopin's hand-written correction in FEJ. The correct text was also introduced into EE2.
